Gmail sees.
Every DMARC tool infers your standing from DNS and aggregate reports. Google Postmaster Tools is Gmail grading the mail it actually received from you. We put that verdict next to your DNS, and we tell you when the two disagree.
0.04% of Gmail's 0.10% limit
Gmail's numbers, judged on Gmail's lines
Four daily rates and eleven graded requirements, refreshed every morning, read straight from Google.
The number the mandates are judged on
The user-reported spam rate, day by day, against Google's own lines: a warning at 0.10%, the rejection line at 0.30%. Plus authentication success, TLS in transit, and delivery errors, measured on mail Gmail received from you.
Requirement by requirement
SPF, DKIM, alignment, DMARC policy, message formatting, DNS, encryption, one-click unsubscribe, honoring unsubscribes: each one compliant or needs work, in Gmail's words, not our inference.
What it will not do
It never invents a grade. Google publishes only at meaningful volume, so a quiet domain shows history and says so; a reading older than 14 days is treated as no reading, never a pass. And Gmail speaks for Gmail: the Microsoft card stays a DNS read.
When Gmail disagrees
Your compliance card for Google and Yahoo is normally a DNS inference. Once Postmaster is connected, Gmail's own grades either confirm it, and the card says Confirmed by Gmail, or contradict it, and the card flips to at-risk with the reason, instead of leaving you a false green.
A spam rate over the line, or a requirement Gmail grades as needing work, becomes an action in your queue the morning the sync sees it, with the alert on every channel you have on. The connection is read-only: nothing about your sending changes.
One DNS record, then it runs itself
Connect from the Deliverability tab
We register your domain with Google and hand you a verification TXT record. On Cloudflare or Route 53 it is a one-click staged change; elsewhere, paste it.
Google verifies, we sync daily
Once the record resolves, the first grades arrive within a day or two. From then on the tab refreshes every morning with a trailing 90 days.
Read it beside your DNS
Spam-rate chart, the rates card, and every requirement's grade, with the gap between what Gmail measured and what your DMARC reports imply called out when there is one.
No mail is redirected and no Google account of yours is linked; you prove control of the domain and Google grants us read access to its report.
